MAINTENANCE ON CHASSIS AND ENGINE 103
9.27Adjusting chain tension
Warning
Danger of accidents Danger caused by incorrect chain tension.
– If the chain tension is too high, the components of the secondary power train (chain, engine sprocket, rear sprocket, bearings in
transmission and rear wheel eccentric element) are under additional load. Apart from premature wear, in extreme transmission
output shaft or the drive chain may snap. Conversely, if the chain is too loose it may jump off the engine and rear sprockets,
causing the rear wheel to lock up or even leading to engine damage. Check for correct chain tension and adjust if necessary.
– Park the vehicle on a horizontal surface and shift gears to neutral.

– Push the upper chain section at the end of the chain sliding component upwards to
measure the chain tension .
Info
The lower chain section must be taut.
Chain wear is not always even, so you should repeat this measurement at differ-
ent chain positions.
